Commonwealth v. Carkhuff

Summary

The Massachusetts Supreme Judicial Court affirmed suppression of evidence obtained after a State trooper stopped the defendant’s vehicle without individualized suspicion near the Cobble Mountain Reservoir. The court held that the suspicionless stop, implemented as a security measure following the September 11, 2001, attacks, did not satisfy constitutional requirements for a roadblock or administrative seizure because motorists received no prior notice and the intrusion was not adequately minimized. The court grounded its analysis in article 14 of the Massachusetts Declaration of Rights.

Holdings

1. A suspicionless stop of vehicles near a potentially vulnerable facility must be conducted as part of an administrative screening scheme whose purpose is other than gathering evidence for criminal prosecutions and must be limited and no more intrusive than necessary to satisfy the legitimate administrative need. The reservoir stop failed that requirement because motorists received no prior notice or warning and had no meaningful opportunity to avoid the encounter.
2. The evidence obtained as a result of the unconstitutional stop was properly suppressed.

Questions Presented

1. Whether the suspicionless stop of the defendant's vehicle as part of a reservoir-security program violated art. 14 of the Massachusetts Declaration of Rights.
2. Whether the stop could be upheld as a reasonable administrative seizure or screening procedure designed to protect a vulnerable water-supply facility.
3. Whether the evidence obtained after the stop was subject to suppression.

Disposition
